Abstract (en)
Mesoporous catalyst for purifying lean burn NOx emission including a mesoporous material which substantially has pores with a diameter of 2 to 50 nm and a specific surface area of 100 to 1,400 m 2 /g, and 0.01 to 20 mass% of a catalyst with an average particle size of 1 to 20 nm which is supported on the mesoporous material and contains platinum.
